GHURN-MOTOR.

SPEOIFICA'I'IONQ1IMIJg part of Letters Patent No. 231,534, dated August 24, 1880. Application filed J anuatry 31, 1880.

T all whom itmay concern Be it known that I, SAMUEL T. CARTER, of

Tama City, in the county of Tama and State of Iowa, have invented oertain'new and useful Improvements in Ghurn-Motors; and I do hereby declare the following to be a full, elear, and exact description of the invention, suoh as will 'enable others skilled in the art to which it appertains to make aud use the same, reference being had to the aceompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in churnmotors, the object being to provide a oheap and effeotive motor for churns, that the operation of ehurning may be performed. without the uecessity of a persona-l attendant; and to this end my invention consists in eertain details of eonstruotion and arrangement of parts in a churn-motor, as wi1l hereinafter be deseribed, and pointed out in the claim.

In the aeeompauying drawings, Figure 1 is a side elevation of my improved ehurn-motor,

and Fig. 2 isa similar view of a modification,

and Fig. 3 shows the churnmotor having a regulating-brake applied thereco.

A represents a suitable frame having a platform, B, projecting lateraily therefrom, on

which is placed or snitably secured an e1ongated ohurn-receptaele, C, having outwardlyflaring ends a a, to prevent the cream fro1n being thrown or splashed over the top of themceptacle.

D is a cover removably secured to the top of the churn, and profided with an elongated slot for the admission and operation of the dasher-rod E, as wiii hereinafter be deseribed.

Mounted on the frame A is a train of gearing, consisting of the main wheel l, seco d wheel, G, and erown-wheel H, the shafts to whieh the wheels are seeured being provided with suitable pinious, with which the wheels mesh or engage, so that rotary movement applied to the shaft of the main wheel F will be transmitted to the shaft on which the crowuwheel H is secured.

The main winding shaft I is preferably pro vided with a drum, J, to which is made 'ast one end of a oord, ehain, or metallic ribbon, K, the opposite and free end of whieh is secured to a weigh'r, L, which latter may be made adjustable in any desired marmer, either by em ploying a rod and using; slotted weights, to be applied or removed as desired, 01 by using an open box and placing any desired weight therein, the box being attached to the lower and free end of strap or ribbon Kby means of a bad or other suitable devices.

To the \i-indingshaft I is rigidly secured a ratchet, M, while the main wheel F is provided with aspring-pressed pawl, d, which engages with the teeth of said ratchet in one direction, and thus allows the weight to be wound up on the shaft, and the latter locked to the man wheel to revoive the same as the weight descends.

Below the crown-wheel H is pivoted the verge N, the lat-ter being pro"ided with a olutch-rod, O, which projects dowuwardl y, and has se eured to its lower end the upper end of the tubular dash-rod P, by a setscrew, P, or other equivalent device. Q, is the churndash, which is attaohed to or formed integral with the dash-rod.

When the ribbon or strap to which the weight is secured is wound npon the shaft a rotary motion will be imparted to the crown-wheel, whieh in turn imparts an oseillating movement to the "erge, which latter movement is trans mitted to the ehurn -dash; and hence the motor being ouce set in motion, the operation of ehurning is eflected by the motor without the necessity of any attendant being present to superintend the work.

Instead of attaching the dash to the lower end of the clutch-rod 0, on ordiuary pendulumweight might be seoured thereto and serve to regulate the speed ofthe motor, while the shaft to which the crown-whee] is attaohed may be oonstructed t0 project outwardly, and be i'ashioned into crank form, as shown in Fig. 2.

In such construction the wrist-piu q is preferably provided with a rolier, q, which en gages in the elongated slot r, formed in the cross-head B, to whieh the dasher-rod is secured. 'lhe 1atter insures a reciprocating moxemeut of the churn-dasher instead of an oscillatin g movemen t, as hereinbei'ore set forth.

When the dasl1er is eonnected drectly with the lower end of the clutch-rod an adjustable brake may be employed to regulate the speed of the motor, as illustrated in Fig. 3, wherein IOO the second wheel of the train of gearng is provded with an outwardly-prqjecting flange, S, upon which rests the brake-shoe S, t11e latter beng attached to the pivoted brake-lemr T. 5 The brake-leveris provided with any desired number of notches for the adjustment of the weight U. By varying the position of the weight U 011 the lexer the 'ricton on the sec 0nd wheel may be varied at pleasnre, and thus 10 a constant force may be exerted on the chu1ndasher throughout the unwindng of the stra-p t0 which the weght is secured.

Having full y descrbed II1 ynventon, what I claim as new, and desre t0 secure by Letters 15 Patent, is

SAMUEL TALOR OARTER.
